UL has issued a 25-year type certificate to EWT for its DW61-1MW turbine. EWT’s 25-year life certificate can reduce the levelised cost of energy (LCOE) of wind projects by up to 8%.
The 25-year type certificate covers products released from 2020. To issue the type certificate, UL assessed the turbine’s ability to handle the additional loads from the extended operational life as well as ageing, wear and potential faults from longer operations. EWT plans to obtain similar length certification for other models.
